[PATCH v2] media: ttpci: fix av7110 build to be compatible with CONFIG_INPUT_EVDEV

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build when CONFIG_INPUT_EVDEV=m and DVB_AV7110=y.
Only build av7110_ir.c when CONFIG_INPUT_EVDEV is compatible with
CONFIG_DVB_AV7110.

Fixes these build errors:

av7110_ir.c:(.text+0x1223ac): undefined reference to `input_event'
